6 Claims.

This invention relates to sacking machines and is particularly adaptedtobe usedin connection with combines and the like.-

The primary object of the invention is to provide a mechanism that willaccommodate two or more sack holders thereon;

Another object of the invention is to provide a mechanism wherein whileone sackis being filled another sack can be sewed.

A still further object of the invention is to provide a mechanism thatwill-shake the ma terial being fill-ed into the sack towards the bottomof the sack, at the same time the sack is being filled.

A further object of the invention is to combine a sack sewing platformwith-the sacking operation in one compact unit.

These and other incidental objects will be apparent in the drawings,specification and claims a to follow.

Referring to the drawings:

Figure 1 is a plan view of the sacking mechanism mounted on a platform,for instance a combine.

Figure 2 is a sectional view, taken on line 2-2 of Figure 1, looking inthe direction indicated.

Figure 3 is a detail plan view of the s ack holding clamp.

figure 4 is an end view, looking in the direction indicated, takenonline4-4 of Figure 1.

Figure 5 is a plan detail view of the raising and lowering mechanism.

Figure 6 is a fragmentary sectional view of the turntable lockingmechanism.

In the drawings:

I is the combine having the usual grain elevator 2, and the usualsacking platform 3, upon which my new and "improved sucker is mounted.Within the platform built a circular track 4, above which is mountedtheplatform or turntable 5. The turntable revolves upon the trunnion wheels6, which are mounted upon the turntable by suitable brackets I, and runon the circular track 4; A supporting column 8 is fixved ly mounted tothe center of the turntable 5 by the hub 9, said hub 9 being securelyfixed to the turntable by the flange ll]. of the pedestal 8 may berotatably mounted within thebearing H. The bearing may not be necessary,but I show the same in this drawing for the purpose of making theassembly more rigid.

Two additional upright columns l2- are fixedly The lower end 1 on themain column 8 by suitable fastening means I Guide rollers l8 aremounted-upon the arms l5 and bear against the inner surface of the guideplates It. On the outer ends of the arms |-5, rollers lflware rotatablymounted, the pur- 6 pose of which will be later described.

On the upper ends of the plungers Hl are mountedsack holder mechanism,which we will now describe. Circular ring 20, about which the sack 2| ispositioned for holding the sack, is 10 mounted onthe plunger by the arm22 and held in an adjusted position by the collar 23 mounted upon theplunger I4. The collar is held in any desired position by the hand setscrew 24. After the sack has been placed about the ring 20, a

secondary ring 25 is placed thereaboutand locked thereon by :a lever 26,mounted within the hinged link 21, which in turn ishingedly connected tothe band 25 at 28. The end 29 of the lever 25 engages thehook 30 of theopposite end of the ring 25, after which the lever 26 is forced pastcenter bringing the ends. of the ring 25 together, similar to a brakeband. The friction engagemerit members 3| will then bear against thesack I, which is trained about the inner ring 5 2!) locking the sametherebetween.

The ring 25 is mounted to a bracket 32, which is p-ivotally mounted lothe slidable sleeve 33 at 34, as shown in Figure 4. The sleeve 33 israised allowing the bracket 32 land the ring 253 3 0 to be movedawayfrom the ring 20, and a holdingarm 22A is provided for the purpose ofholding this unit in a raised position, so that the sack 2| can bereplaced or taken oil. Raising the bracket arm 22 upward on the plungerI4, 35 thus disengaging the dog 35, from a corresponding notch withinthe sleeve 23, allows the revolving of the brackets 22 and 32 about theplunger so that the rings 20 and 25 can be moved away from the sack 2|allowing access to the sack for sewing :and removing, The sacks 2| restupon special guides or receivers 36 that are shaped to conform to thebottom of the sack, and these guides are in turn fixedlyv mounted to theupper surface of the turntable 5.

In my new and improved sacker, the primary object is to not only holdthesack but also to shake the contents of the sack towards the bottom ofthe same permitting a more solidly filled sack and this is accomplishedin the following, mannor. The arms I5, having the rollers l9 mountedthereon, are brought into engagement with a cam 31, .and as the camrevolves in the direction indicated it will raise the arms I5 and theplungers lijas shown in Figures 2 and 4. When the cam reaches the pointshown in Figure 2, the rollers l9 will drop ofi of t the end 38 allowingthe plunger M to fall quickly. dropping the bottom of the sack upon thereceiver or brackettli. This forces the contents of the sack towards thebeta tom, packing the same as if it were being done by hand. Byobserving the shape of the cam it will be noted that as the cam revolvesit will repeat this operation, raising the plunger slowly and droppingit quickly. 'Iheplunger or sack holder that is registered with thefilling spout 39 is the one that will be agitated as just described. Theopposite sack holder, which is one hundred and eighty degrees opposite,will be stationary, as its raising and lowering mechanism is out ofengagement with the cam 31. This permits the disengagement of the sackfrom the holding rings and revolving them out of position, as beforedescribed, and the sewing of the sack by the sewer can then beaccomplished, after which the sack is tipped over into the chute 40 andanother sack secured to the rings 20 and 25 and locked thereto asheretofore described.

In order to settle the materials being filled into the sack towards thebottom of the sack it is desirable to drop the sack forceably after thecam 31 reaches the top, but it is also desirable to hold the upper partof the bag under tension when this operation takes place. Therefore theplungers M are held in raised position by the springs 4|, having theirupper ends secured to the lower side of the turntable 5 and their lowerends connected to the arms I5 of the plungers l4. When the sack underthe hopper 39 is filled to the desired point the operator or sack tendertakes hold of the handles 42 and revolves the turntable 5 one hundredand eighty degrees in the direction of the arrows. This movement can nottake place until the cam 31 has raised the arm IE to the top position,due to the fact that the roller 43 engages the front surface 44 of theframe 45, best shown in Figures 2 and 4, when the arm l5 reaches thetop. The rollers 43 can then be forced over and upon the inclinedsurface 46 of the frame 45. The downward weight of the filled sack 2IAwill assist in the revolving of the turntable from there on due to thefact that the roller 43 holding the arm l5 from downward move- .mentwill be running down the inclined surface A suitable shut-off valve 41is provided for shutting off the supply while the turntable is beingrevolved, taking a filled sack away and bringing in an empty oneunderneath the spout 39.

The cam 31 is driven by the driving sprocket 52, which may be anysuitable drive relative to the combination of the sacker with thecombine. A chain 53 drives the sprocket 54, which is fixed to the cam31.

The turntable 5 is held from turning by locking dogs 48 underneath thebrackets 36. The dogs 48 register with notch 49 of the foot pedal 50,and when the foot pedal 50 is pushed down against the spring 51 thenotch 49 will be released from the dog 48 permitting the turntable 5 tobe revolved.

I do not wish to be limited to this particular form of mechanicalembodiment, as other types of construction could be employed, stillcoming within the scope of the claims to follow.
